APPARATUS FOR DISPOSING 0F NOXIOUS GASES.

Specification of Letters Patent.

Patented Dec. 14, 1909.

Application filed April 1 0, 1909. Serial No. 489,198.

To all whom it may concern:

' Be it known that 1, WILLIAM H. SARTAIN, a citizen of the UnitedStates, residing at Columbus, in the county of Franklin and State ofOhio, have invented certain new and useful Improvements in Apparatus forDisposing of Noxious Gases, of which the following is a specification.

My invention relates to apparatus for dis posing of noxious gasesincldent to the rendering of lard or oifal, and the objects of myinvention are to provide comparatively simple and inexpensive means forremoving noxious gases or vapors from a rendering tank; separating thegases from the steam and disposing of such gases without permittingthesame to mingle with the atmosphere.' These objects I accomplish in themanner illustrated in the accompanying drawing, in which is shown partlyin section and partly in elevation, my improved means for treating anddisposing of noxious gases. v

It is a common expedient in packing houses and similar places to renderlard or treat waste products, by placing the same in a closed receptacleknown as a rendering tank, and subjecting the same to the cooking actionof steam discharged into said tank from a boiler or other suitablesource of steam supply. As a result of this treatment of the contents ofthe tank, noxious gases are formed which when permitted to escape to theatmosphere, create an ext trcmely disagreeable odor in the neighborhoodof the plant, which odors are at times carried to comparatively longdistancesfrom the tank. By the construction of the apparatus which Ihave provided, the gases generated in the rendering tank, are disposedof and the odor in the neighborhood of the tank, dispensed withentirely.

Referring to the drawing, 1 represents a suitable form of renderingtank, which is provided with a valve'controlled steam inet pipe 2,preferably in its lower end portion, and an outlet pipe 3 in its upperend portion. The outlet pipe through the medium of pipe sections 3 and 3leads through the u per end of a vertical tank or cylinder 4, which isdisposed at a reasonable distance from the tank 1. Above the tank 4, thepipe section 3 is separated and the sections formed by such separationconnected by a suitable form of T-coupling 5, into which leads a watersupply pipe 6, which may run from any suitable source of water pressure.Within the upper portion of the charges within or immediately beneaththe fire-box of a furnace l1. As indicated in the drawing, the tank 4 isnormally supplied Wi water, which rises tank 4, I suspend a coiled tube7 the upper to the height of the center of the horizontal member of theoutlet pipe 9.

As a result of the rendering of lard, ofi'alj or other material withinthe tank 1, it is obvious that gas is generated in said tank and themingled steam and gas finds an outlet through the pipe 3. Beforereaching the tank 4, however, this'mixture is subjected to the action ofa comparatively small stream of cold water, which enters the pipe arm 3through the pipe 6 and operates to condense the steam, therebyseparating the gas from the steam. As will readily be understood,however, a certain per cent. of uncondensed mingled steam and gas, maypass into the upper portion of the'tank 4, thence downward through thecoil 7, the contact with which insures the; completion of the condensation. The water from the'condensation joins the body of watercontained in the lower half of the tank, while the gas which isseparated by the condensing operation, passes outward through the pipe10 to the fire box of the furnace, where it is completely consumed. Anygas which may pass downward through the coil and which is only releasedfrom the volume of steam by contact with the comparatively cold waterwithin the tank, may rise into said tank 4 and. pass outward through thecoil openings 8 and gas pipe 10.

Owing to the provision of the utlet pipe.

9, it will be understood that the .vater in the tank 4, will bemaintayled at substantially the same level, inasmuch as slid outlet pipewill serve to carry/away th; surplus water which may be directedtherein, as a result of condensation of steam and the supply from thepipe 6.

By the means and operation described, it will readily be understood thata complete separation of the mingled gas and steam, is effected, andthat the being consumed at the furnace, the atmosphere in theneighborhood of the rendering tank, will be free from contamination. v I

What I claim, is:

In an apparatus for the disposal of noxious gases, the combination witha rendering tank having a steam supply pipe, of a second watercontaining tank having an outlet pipe 15 as described, a coiled tubeWithin the upper portion of said second tank and having openings in itsupper portion, a pipe connecting the upper end of the rendering tank andsaid second tank and connecting with said coiled tube, a water pipeleading into said connecting pipe, and a gas pipe leading. from theupper end of said second tank to a fire containing structure. v I

In testimony whereof I aflix my signature in presence of two witnesses.

WILLIAM SARTAIN.
